> To be easily seek and positioned read distributed file, the length of encrypted file
should be the same as the length of plain file, and the positions have 1:1 mapping.  So in
this JIRA we defines distributed file cipher InputStream(FSDecryptorStream) and OutputStream(FSEncryptorStream).
The distributed file cipher InputStream is seekable and positonedReadable.  This JIRA is different
from HADOOP-10151, the file may be read and written many times and on multiple nodes.
